The purpose of this research is to be grasp the relation between lumbago incidence rate and research hypothesis in the effects of sex life of the middle-aged couples in Taejon area upon lumbago. This writer had questionaired the 400 middle-aged couples in Taejon city - Jung-gu, Seo-gu, Dong-gu, Yuseong-gu, and Taedeok-gu - from June 1, to June 30, 1998. Of them, total 209 question papers were drawn back; male 102, female 107. Analysis of the data is as follows; 1. 145(69.37%) subjects of total 209 had low back pain experience after their sexual lives. 2. In the number of sexual times a week, low back pain incidence were the most rate in 1-2 times as 41.55%, each other had a statistically significant relation (P<0.01). 3. In age and lumbago incidence rate, the 30s was 37.75% and each other had a significant relation (P<0.05). 4. In weight and lumbago incidence rate, the level of 50kg~60kg was highest and each other didn't have a significant relation (P>0.05). 5. In the mean sexual time, the period of 11~20 minutes was 29.47% and each other had a significant relation (P>0.01). 6. In a day time of sexual life and lumbago incidence rate, midnight was the highest rate(36.23%) and each other didn't have a significant relation (P>0.05). 7. In the lumbago incidence rate according to bedroom structure of sexual life, a bed was 38.17% and each other had a significant relation (P>0.05). 8. In the lumbago incidence rate according to sexual posture, a normal position showed the highest rate(46.12%) and each other didn't have a significant relation (P>0.05). According to the results of our research, lumbago has relation to the number of sex life a week, age, the mean time of sexual life, and bedroom structure of sexual life. So it is thought that it is necessary that middle-aged couples periodically study the educational programs to make an prevention education for low back pain the key points.

This study aims to prove the mediating effect of emotion dysregulation and perceived social support in the relationship between covert narcissism on the relation addiction. The researchers surveyed college students for about 3 weeks through a questionnaire on college campus or with the help of their colleagues and professors. The subjects were 362 students. SPSS, AMOS and Mplus were used for statistical analysis, correlation analysis and structural equation analysis. The conclusions are as follows : First, emotion dysregulation, relation addiction and covert narcissism showed positive correlation and covert narcissism, emotion dysregulation, relation addiction and perceived social support showed a significant negative correlation. Second, it was found that after investigating the mediation effect of emotion dysregulation and perceived social support in the influence between covert narcissism and relation addiction, emotion dysregulation turned out to have a significant mediating effect while perceived social support did not. Third, dual mediating effect was significant in emotion dysregulation and perceived social support in the influence between covert narcissism and relation addiction. These findings proved that covert narcissism, emotion dysregulation, perceived social support are variables that effect relation addiction, and also clarified that emotion dysregulation is a strong mediating variable in the influence between covert narcissism and relation addiction. Finally, when counseling a client with the same tendency as covert narcissism, it gives an opportunity to be aware of the emotional problem and an opportunity to positively perceive its own social resources, so as not to reach interpersonal problems such as relationship addiction pointed out the need for an approach.

This study is intended to suggest fundamental data necessary for developing MBTI program that can help improve interpersonal relation skills of nursing science major students and their cohesion. This study is pre-experimental research by one group pretest-post test design to examine the effect of MBTI(Myers and Briggs Type Indicator) basic program on the interpersonal relationship between nursing science major students and their group cohesion and the relationship between interpersonal relationship and their group cohesion. I selected 39 of sophomore students in the department nursing science of K university in I metropolitan city as test group. 35 of them joined post-test. Pretest and MBTI basic program were done before conducting MBTI program. Collected data were analyzed by SPSS window 7.5. The difference in test group before and after conducting program was examined by paired t-test. The correlation between interpersonal relationship and group cohesion was measured by using Pearson Correlation Coefficient. The findings are as follows. $\cdot$ The difference before and after conducting MBTI program by sub-factors of interpersonal relation: There was no significant difference, as the average figure of interpersonal relation in test group was 87.22 before conducting MBTI and 85.08 after conducting MBTI respectively. The average figure of sensitivity among the sub-factors of interpersonal relation was 7.71 before conducting MBTI and reduced to 7.08 after conducting MBTI and there was significant difference between before and after conducting MBTI(t=-2.484, p=.018) $\cdot$ The difference in group cohesion before and after conducting MBTI program: The average figure of group cohesion in test group was 56.68 before conducting MBTI and increased a bit to 56.80 after conducting MBTI\, but there was no significant difference between them. $\cdot$ The relationship between interpersonal relationship and group cohesion before and after conducting MBTI: As the relationship between interpersonal relationship and group cohesion before and after conducting MBTI is examined, there was positive correlation of the significance level. p<.05 before conducting MBTI(r=.320, p=.047), and of the significance level, p<.01 after conducting MBTI(r=.780, p=.000). The investigation on the relation between sub-factors of group cohesion and of interpersonal relation before conducting MBTI basic program revealed that there was positive correlation between openness, reliability, friendliness and satisfaction, and group intervention, between receptivity among group members and reliability, and between group atmosphere and satisfaction. The investigation on the relation between sub-factors of group cohesion and of interpersonal relation after conducting MBTI basic program revealed that there was positive correlation between openness, communication, understanding, friendliness and satisfaction. and group intervention. There was positive correlation between receptivity among group members and openness, communication, understanding, friendliness and satisfaction. There was positive correlation between openness, communication, friendliness and satisfaction, and group atmosphere. Based on the above findings, I realize that MBTI basic program is essential to the improvement of group cohesion. In addition, it is shown that the sub-factors of interpersonal relation such as openness, communication, friendliness, satisfaction, and understanding, and the sub-factors such as group intervention and receptivity among group members are major factors to improve interpersonal relationship and group cohesion. So, the future MBTI program should include sub-programs that deal with the above factors to improve interpersonal relationship and group cohesion.

This study was performed to investigate the relationship between mandibular midline shift and anteroposterior first molar occlusal relation, and their effects on the mandibular height and the occlusal plane angle. For this study, 49 patients with temporomandibular disorders were selected. They did not show facial asymmetry and their facial midline coincide with maxillary dental midline. Upper and lower mandibular impression were taken and the casts were fabricated. Amount and direction of the mandibular midline shift and the anteroposterior shift between the two occluding first molars were measured on the casts. Several items related to height such as mandibular height from top of the articular surface of the condyle to curve changing point between antegonial notch and mandibular angle, condylar height which was the vertical distance from the articular surface to retroepicondyle of the condyle, and sigmoid height from the deepest point of sigmoid notch to the curve changing point and the occlusal plane angle were also measured on the panoramic and on the transcranial radiographs. Correlation between midline shift and anteroposterior first molar relation and comparison between right and left mandibular height by the midline shift and the first molar relation were analysed by SPSS windows program. The results of this study were as follows : 1. Mean amount of midline shift in the subjects with midline shift were 2.0mm for both side, respectively. The first molar relation of the ipsilateral side of midline shift showed Angle class II tendency and the contralateral side showed Angle class III tendency, which meant drift of the dentition to the side of the midline shift. 2. The occlusal plane angle on the panoramic radiograph were $13.0^{\circ}$ in right, and $12.5^{\circ}$ in left side, and their were no correlation between occlusal plane angle and mandibular midline shift and the first molar occlusal relation. 3. Angle's classification for both sides of the first molar relation were same in about half of all the subjects. Amount of deviation from class I first molar relation, however, were decreased in the contralateral side of observed side. 4. Mandibular height of the ipsilateral side to which mandibular midline shift showed tendency of lower than that of the contralateral side, and there was a tendency that the height was higher in class III subjects, then class II subjects, and lower in class I subjects. However, condylar height did not show any difference in the subjects with midline shift and also show no difference by the first molar occlusal relation.

This article tries to compare exchange relations between welfare and dictatorship in the East Germany and the North Korea. Unlike capitalist welfare aiming at correcting market results socialist welfare has been proposed to satisfy people's basic needs, but it had operated as instrument of dictatorship. Relation between welfare and dictatorship could be distinguished as hard exchange and soft one in line with social construction of welfare. Welfare-dictatorship relation in East Germany had developed from its formation(1949-1970s), crisis(1980s) and dissolution(1989-1990). There had established hard exchange relation in which the legitimacy of dominance had debted to welfare as social rights. While crisis of the exchange relation had been modest in a form of insufficient supply of consumption goods, it was one of the elements of collapse of dictatorship, leading to the unification with West Germany. The journey of the exchange relation in North Korea can be characterized by its formation(1948-1980), crisis(1990s-2000s), and transformation(2010s). Unlike East Germany, welfare was socially constructed as gift form the ruler to the ruled, which made the combination of welfare and dictatorship loosely coupled. Although economic crisis was severe compared to East German one the rulers have succeeded maintaining dictatorial dominance by creating dual exchange relation. They separated core group and subordinated one supporting the former at the expense of the latter. They blocked out most of the people from soft exchange relation making bad use of muddling-through life style dependent on market activities. This strategy led to a 'dictatorship neutral welfare extinction'. Taking the high degree of institutionalization of newly establishing welfare-dictatorship relation into account, lives of most people are hardly expected to be improved by gift by their rulers even if North Korean economy will recover in the future.

The main purpose of this research is to investigate the effect of Korean adults' perception of parent-child relation on their self-efficacy, child rearing practices, elderly parent care practices, and happiness. In this study the parent-child relation is a relationship between the adults' parents and the adults. The participants in the study were adults (2,632; male=1,275, female=1,357) with children in primary, secondary, and/or university, with an average age of 45.44-years-old (male=46.96-years-old, female=44.10-years-old). The results showed a direct influence of the adults' perception of parent-child relation on their self-efficacy and their child rearing practices, and an indirect influence on their happiness. This indicates that a more positive adult's perception of parent-child relation leads to higher self-efficacy and greater devotion to their child rearing practices. And furthermore, an elevated self-efficacy enhanced their happiness. Gender differences were found for the influence of adults' perception of parent-child relation on elderly parent care practices. For Korean male adults, a more positive perception of parent-child relation lead to a more active participation in elderly parent care practices. However, for Korean female adults no direct influence was found. Based on these results, a discussion of the influence of adults' perception of parent-child relation on the adults' psychological characteristics and family-members relationships is provided.

Z. Cao had proposed NFRM(new fuzzy reasoning method) which infers in detail using relation matrix. In spite of the small inference rules, it shows good performance than mamdani's fuzzy inference method. In this paper, we propose 2. Cao's fuzzy inference method using learning ability witch is used a gradient descent method in order to improve the performances. Because it is difficult to determine the relation matrix elements by trial and error method which is needed many hours and effort. Simulation results are applied linear and nonlinear system show that the proposed inference method has good performances.

This study suggests a method for extending XMDR to integrate and search legacy system. This extension blends MSO(Meta Semantic Ontology) for the management of metadata, ML(Meta Location) for the management of location information, and Topic Map which is the standard language used to represent semantic web. This study refers to it as TMDR(Topic Map MetaData Registry). As an intelligent layer, Topic Map functions like an index. However, if the data frequently changes, the efficiency of Topic Map may drop. To solve this problem, the proposed system represents the relation among metadata, the relation among real data, and the relation between metadata and real data as Topic Map. The represented Topic Map proposes a method to reduce the changing relation among real data caused by the relation among metadata.

In this paper, we propose a method to extract isa/instanceOf relation from category structure. Existing researches use lexical patterns to get isa/instanceOf relation from the category structure, e.g. head word matching, to determine whether the given category link is isa/instanceOf relation or not. In this paper, we propose a new approach which analyzes other category links related to the given category link to determine whether the given category link is isa/instanceOf relation or not. The experimental result shows that our algorithm can cover many cases which the existing algorithms were not able to deal with.
